We demonstrate that TBVE works in our Fastspeech 2 [1]} inspired TTS framework which uses a variance adaptor to predict phone-wise frame durations rather than an attention-based encoder-decoder approach [2]}, [3]}.

We demonstrate that even without the usage of speaker embeddings, speaker information can be extracted effectively from acoustic context.

We demonstrate that utterance embeddings and a reference encoder improve continuity in the zero-shot setting, potentially removing the need for finetuning on extra data from target speakers.
